To ail whom, it may concern:

Be it known that we, WILLIAM SCHAEEEE and JOHN SCHAEFER, residing in the city of Wheeling, Ohio county, Test Virginia, have invented new and useful Improvements in Apparatus for Treating Black-Plate for Tin ning, of which the following is a specification.

Our invention is an improvement in apparatus for treating black-plate fortinning; and

lo it consists in the novel features hereinafter described, reference being had to the accompanying drawings,'which illustrate one form in which we have contemplated embodying our invention, and said invention is fully disclosed in the following description and claims. In the drawings, Figure-l represents a side elevation of our complete apparatus. Fig. 2 represents a top plan View ot a portion of the endless carrier for the black plates. Fig. 3 zo is a detail perspective view of one ofthe rigid fingers and one of the movable fingers. Fig. 4 represents a transverse vertical section through the annealing-furnace, showing the endless conveyer, one part within the fur- 2 5 nace and another part within the coolingtrough below the furnace. Fig. 4a represents a detail viev1 of a portion of the endless conveyer, one of therevoluble supports therefor, and the stationary device for separating the go rigid and movable fingers to allow the plates to be discharged therefrom. Fig. 5 represents a longitudinal vertical section of the rolling device for rolling the plates after they leave the drying-furnace. Fig. 6 is an end view of the same.

In the drawings, D represents an annealing-furnace of any desired construction, provided with a longitudinally-disposed passage d, extending therethrough. 4o e represents a bath or tank containing an acid solution, located in line with 4the longitudinal passage through the annealing-furnace, for pickling the plates. n represents a similar bath or tank containing water for washing the plate and removing scale therefrom, and h is a drying-furnace of any desired construction and which may be constructed similar to the annealing-furnace D and having a longitudinalv passage extending 5o therethrough, the said passages in said fur- 1 means. be apparent from Figs. 2, 3, said carrier consists of` two endless chains a a, vwhich are connected at intervals by trans- I verse bars a a', rigidly secured thereto, each i bar being provided with a series of rigid'n- 7o .as for rocking the same. treated are inserted between the fingers a2 a4 on the end of the carrier before said carrier 85 enters the annealingfurnace D, and the naces and the tanks c and n being located in astraight line. S represents a cooling-trough extending underneath the said tanks and furnaces and vertically in line with the longitudinal passages through said furnaces, as shown in Fig. 4, the said tank S being snpplied with water.` y

A represents an endless carrier which passes though the annealingfu rnace D, the picklingl bath e, the water-bath n, the drying-furnace 6o h, and returning through the cooling tank or trough S, said carrier being guided and supported throughout its length by suitable stationary rollers and driven by any suitable The construction of said carrier will and 4. The

gers a2, extending in the general direction of the carrier. Adjacent to each of the bars ct' i is a transverse rock-shaft a?, mounted in bearings Acarried by the chains a, and each of said rock-shafts is provided with a series of movable fingers a4, rigidly secured to the rockshaft, each of said fingers being preferably provided with a downwardly-extending retaining-arm a5, which engages one of the rigid fingers a2 or a plate resting upon said rigid 8o lingers, as the case may be. Each of said rock-shafts is provided with an operating-arm The plates to be plates will be held between said fingers and carried through the annealing-furnace, the pickling-bath, the water-bath, and the drying-furnace and successively treated by these 9e devices.

Beyond the drying-furnace h we provide a stationary cam A (see Figs. 2 and 4a) in the path of the operating arms or levers a, Said arms or leversv are so constructed, as shown in Fig. 2, that they have a broad bearing portion which engages the said stationary cam A', said arms or levers having the portions thereof nearest the rock-shaft reduced in width, as shown in Fig. 2, so that said arms zoo will disengage the cam A upon the further movement of the carrier. We prefer to locate the cam A at such a point Yad jacent to the last supporting-roller of the upper series (shown in Fig. l) that the engagement of said operating-arms a6 with said cam A' will cause a separation between the rigid fingers a2 and movable fingers a4 as the carrier passes around said roller, which is indicated at A2in Fig. 4;, so as to allow the plates carried by said iingers to be discharged therefrom, as indicated in dotted lines in Fig. 4a.

Beyond the drying-furnace h we provide a series of vertical pairs of rollers, three pairs being shown, (see Figs. 5 and 6,) the said rollers l l being mounted in asuitable frame or housing and driven by suitable gearing 6 S. Adjacent to the drying-furnace we provide the housing with an inclined series of rollers R, forming an inclined guide or slide upon which the plates are delivered from the endless carrier and slide down by gravity into the bite of the iirst pair of rollers l l. Between the adjacent pairs of rollers we also arrange short conveying-belts c c, which receive the plates from one pair of rollers and carry them to the next pair, the plates being delivered from the last pair of rollers upon a table T or other suitable device. It will thus be seen that after a plate is placed upon the carrier it is carried through the annealingfurnace, pickling-bath, vwater-bath, dryingfurnace, and rollers without being touched by any operator, thus rendering the process a continuous one and dispensing with the handlin g of the plates from one device to another. It will also be seen that as the endless carrier leaves the drying furnace it will return through the cooling-trough S to the annealing-furnace, and during its immersion in said trough it will become cooled.

By the use of our improved apparatus the treatment of black plates preparatory to tinning can be carried on very cheaply and rapidly with the use ot' a very small number of men.

`That we claim, and desire to secure by Letters Patent, is

l. In apparatus for treating black-plate for tinning, the combination with an annealingfurnace provided with a longitudinal passage therethrough, a pickling-bath, and a waterbath, a drying-furnace havinga longitudinal passage therethrough and a cooling-trough extending beneath said baths and furnaces, of an endless carrier having a portion extending through said baths and furnaces and a portion extending through said cooling-trough, substantially as described.

2. In apparatus for treating black-plate for tinning, the combination with an annealingfurnace, a pickling-bath, a water-bath and a drying-furnace, of an endless carrier extending through said baths and furnaces, comprising parallel endless chains, a series of rows of fingers rigidly connected thereto, a series of rows of movable retaining-fingers pivotally secured to said chains, one of said rows being adjacent to each row of stationary fingers, and adapted to coperate therewith to grasp a plate between them, and stationary devices for separating said movable fingers from said stationary iingers,to permit them to discharge the plates carried thereby, substantially asdescribed.

3. In apparatus for treating black-plate for tinning, the combination with an annealingfurnace, a pickling-bath, a Water-bath and a drying-furnace, of an endless carrier extending through said baths aud furnaces comprising parallel endless chains,a series of rows of fingers rigidlyconnected thereto, a series of rows ot movable retaining-fingers pivotally secured to said chains, one of said rows being adjacent to each row of stationary lingers, and adapted to cooperate therewith to grasp a plate between them, an operating-arm for each row of movable fingers, and a stationary device in the path of said arms for separating said movable fingers from said rigid fingers, to permit the plates carried thereby to be discharged, substantially as described.

4:. In an apparatus for treating black-plate for tinning an endless carrier, comprising among its members, a plurality of endless chains, a series of transverse shafts rigidly secured thereto, at intervals, a series of iingers secured to each of said shafts, a rockshaft pivotally secured to said chains adjacent to each of said rigidly-connected shafts, a series of retaining-{ingers on each of said rock-shafts, each finger having a retaining projection extending toward one of said rigid fingers, an operating-arm secured to each rock-shaft, revoluble supports for said chains and a stationary part in the path of said arms for rocking said rock-shafts, substantially as described.
